Struct CodexAdapter 

pub struct CodexAdapter;

The Codex CLI adapter: tails ~/.codex/sessions/YYYY/MM/DD/rollout-*.jsonl and converts records to user_message / agent_message / thinking / tool_call / tool_result events. Stateless; the tailer thread holds all mutable state.

Experimental

This adapter is built against the researched Codex CLI rollout format (https://github.com/openai/codex) without real captured fixture files. The parser handles the documented record types (session_meta, turn_context, response_item, event_msg) and degrades gracefully on unknown types. If you encounter a session that produces 0 steps despite having a transcript, run HH_DEBUG=1 hh run -- codex ... and file an issue with the debug output.
